-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
it is now possible to compile and install GCC on the system.
Before doing this, if you are not using the build.sh script,
you will need to call the fetch scripts in order to retrieve
the sources of GCC and its dependencies.
-Reduce difference with NetBSD share/mk
Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
which is anyway patched, so that bsd.gcc.mk is now aligned
on the NetBSD version.
-Clean libraries dependencies, compiles stdc++ only if gcc is
also compiled (it is part of the gcc sources)
-Correct minix.h header sequence, cleanup spec headers.
-Fix cross-compilation from a 32bit host targeting MINIX/arm

. test74 for mmap functionality
. vm: add a mem_file memory type that specifies an mmap()ped
memory range, backed by a file
. add fdref, an object that keeps track of FD references within
VM per process and so knows how to de-duplicate the use of FD's
by various mmap()ped ranges; there can be many more than there can
be FD's
. turned off for now, enable with 'filemap=1' as boot option
Change-Id: I640b1126cdaa522a0560301cf6732b7661555672
Primary purpose of change: to support the mmap implementation, VM must
know both (a) about some block metadata for FS cache blocks, i.e.
inode numbers and inode offsets where applicable; and (b) know about
*all* cache blocks, i.e. also of the FS primary caches and not just
the blocks that spill into the secondary one. This changes the
interface and VM data structures.
This change is only for the interface (libminixfs) and VM data
structures; the filesystem code is unmodified, so although the
secondary cache will be used as normal, blocks will not be annotated
with inode information until the FS is modified to provide this
information. Until it is modified, mmap of files will fail gracefully
on such filesystems.
This is indicated to VFS/VM by returning ENOSYS for REQ_PEEK.

This commit removes the secondary cache code implementation from
VM and its usage from libminixfs. It is to be replaced by a new
implementation.

. test70: regression test for m_out vfs race condition
The following tests use testcache.c to generate test i/o
patterns, generate random write data and verify the reads.
. test71: blackbox full-stack test of FS operation, testing
using the regular VFS interface crazy i/o patterns
with various working set sizes, triggering only
primary cache, also secondary cache, and finally
disk i/o and verifying contents all the time
. test72: unit test of libminixfs, implementing
functions it needs from -lsys and -lblockdriver
and the client in order to simulate a working
cache client and backend environment.
. test73: blackbox test of secondary vm cache in isolation

. vfs read_only() assumes vnode->v_vmnt is non-NULL, but it can
be NULL sometimes
. e.g. fchmod() on UDS triggered NULL deref; add a check and
add REQ_CHMOD to pfs so unix domain sockets can be fchmod()ded
. add to test56

. add -l option to list available tests
. add -t option to specify tests to run
. also improve the root check a bit by
not relying on an environment var
. do not print the human-friendly banner & summary
if a test list is given to make the test
results easy to parse

test69 requires superuser powers to adjust the time. This caused
the test to fail when run as a normal user. The patch adds test69
to the setuid list which will allow regular users to execute it.
Patch contributed by Antoine Leca.
This also adds the sys_settime() kernel call which allows for the adjusting
of the clock named realtime in the kernel. The existing sys_stime()
function is still needed for a separate job (setting the boottime). The
boottime is set in the readclock driver. The sys_settime() interface is
meant to be flexible and will support both clock_settime() and adjtime()
when adjtime() is implemented later.
settimeofday() was adjusted to use the clock_settime() interface.
One side note discovered during testing: uptime(1) (part of the last(1)),
uses wtmp to determine boottime (not Minix's times(2)). This leads `uptime`
to report odd results when you set the time to a time prior to boottime.
This isn't a new bug introduced by my changes. It's been there for a while.
In order to make it more clear that ticks should be used for timers
and realtime should be used for timestamps / displaying the date/time,
getuptime() was renamed to getticks() and getuptime2() was renamed to
getuptime().
Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2()
have been updated. In instances where a realtime was calculated, the
calculation was changed to use realtime.
System calls clock_getres() and clock_gettime() were added to PM/libc.
When you provided a string with junk after the terminating nul to a
UNIX domain socket and used bind(2), the canonical path function would
not properly terminate the new string. This caused VFS to return
ENAMETOOLONG on an otherwise valid path name.
Test case is added to test56.

Select(2)ing on UNIX domain sockets was not working properly because
connection state wasn't properly checked/propagated. So selecting for
a read descriptor and closing the write descriptor on the other end
didn't cause select to return. Similarly, read(2) kept blocking while
it should return an error when the other end closed the socket.

if an exec() fails partway through reading in the sections, the target
process is already gone and a defunct process remains. sanity checking
the binary beforehand helps that.
test10 mutilates binaries and exec()s them on purpose; making an exec()
fail cleanly in such cases seems like acceptable behaviour.
fixes test10 on ARM.

So we don't have to figure out which line generated this error by
searching for the subtest/error code combination.
Change-Id: Icca0a776fd19f0f3d250ddb76916f5f932dd9b5e
Adding the bomb function which takes as a parameter a string
to be printed, print it, cleans up and exits with an error
code. It also means they will exit after the first error, unlike
previous behaviour.

test3 performs tests for null pointers but after that still continues
and uses them. This results in segfault's. Fixing this issue by failing
on the first error.
upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
. also make other out-of-memory conditions less fatal
. add a test case for a user program using all the memory
it can
. remove some diagnostic prints for situations that are normal
when running out of memory so running the test isn't noisy
